FIRE PROOF LATH FOR SLATES.

SPECIFICATION forming part of Letters Patent Ne 320,072. dated `Tune16,1885.

(No model.)

To all whom it may concern:

Be it known that we, NVILLIAM H. LANE and LOUIS LANE, both citizens ofthe United States, residing at Newark, in the county of Licking andState of Ohio, have jointly in- Vented a new and useful Form ofFire-Proof Lath for Slates or Tiles, of which the following is aspecifieation.

The object of our invention isto provide, in connection with a netalliclath, a suitable substancc to which the slate can be firmly attached,and which will form a more or less elastic support for the same, therebypreventing breakage, together with provisions for secui-ing closercontact between the slates and lath thus affording a joint proo'againstsnow, rain, &0.

To secure this our invention consists in a hollow or grooved metalliclath incasing and' protecting on three sides a strip or filling of woodor other fibrous substance which it supports, and to which the slate isnailed or screwed in the usual manner. To protect this filling on thetop, and to provide a packing between the lath and slate, we use a stripof asbestns or other firc-proof felt or paper in connection with acement of a similar nature.

In the drawings, Figure l is a section.

A is the metal lath of such form as to support and inease the filling L.Itis Secured to the rafter K by :means of the knce-bolt G and the nuts NN or other suitable devicc.

B is the strip of felt, with its edge at b in \Vhen the filling is thesmall groove in L.

put in, the two sides aa' are pressed together, thus holding' thefilling` and the edge?) firmly. B is further Secured at inter-Vals withthe brad D, and has its edge b' turned over and back, as shown.

The top of the filling-strip L is of such form that the slate F is inclose contact with B, when the slate E rests upon the fold b' and clearsthe side a' of the lath A.

XVhen the slate E is laid,the spaeeI is filled ilush with the cement,which packs the joint as F is nailcd or screwed down.

Fig. 2 is a general View with the parts narked the same, as in Fig. 1.

W'c are aware of the use of asbestns and other felts and cements forpacking and fireproofing, and of the use oi' iron and wood forslate-laths; but we are not aware of the form and combination, as abovedescribed and shown.

\Ve claim and desire to secure by Letters Patent- [he combination, withroofing slates or tiles, of hollow metallic lath ineasing on three sidesa filling of wood or other fibrous material whose exposcd side iscovered by a layer of felt and cement, substantially as shown anddescribed.
